-Subject: [PATCH] core/load-fragment: refuse units with errors in certain
- directives
-
-If an error is encountered in any of the Exec* lines, WorkingDirectory,
-SELinuxContext, ApparmorProfile, SmackProcessLabel, Service (in .socket
-units), User, or Group, refuse to load the unit. If the config stanza
-has support, ignore the failure if '-' is present.
-
-For those configuration directives, even if we started the unit, it's
-pretty likely that it'll do something unexpected (like write files
-in a wrong place, or with a wrong context, or run with wrong permissions,
-etc). It seems better to refuse to start the unit and have the admin
-clean up the configuration without giving the service a chance to mess
-up stuff.
-
-Note that all "security" options that restrict what the unit can do
-(Capabilities, AmbientCapabilities, Restrict*, SystemCallFilter, Limit*,
-PrivateDevices, Protect*, etc) are _not_ treated like this. Such options are
-only supplementary, and are not always available depending on the architecture
-and compilation options, so unit authors have to make sure that the service
-runs correctly without them anyway.
-
-Fixes #6237, #6277.
